Abstract

A press for molding thermoplastic, thermosetting, polyurethane polymeric articles comprises three workstations arranged side by side and including a central molding station (20) and two lateral stations (30A-30B) for cooling and extracting molded articles. Two molds (70A-70B) are rigidly connected to one another and controlled by a transfer pusher (75) which alternately moves the molds from the molding station to either of the cooling and extraction stations. A first presser (22) at the central molding station applies a closure pressure necessary for the material injection, while auxiliary presser (50-60) arranged in each station applies a reduced secondary pressure to the molds at the end of the injection step, during the translatory motion of the mold and during the cooling step.
